Nothing in this patch actually explain what an "IO standard" is,
which is paramount if it should be a generic property.

And if it should be generic, I really want to know why this is a
thing not overlapping with existing generic configs, and exactly
what it is and that it is probable other silicon will have it too.
And we need to discuss if it's the right name.

Looking at what you actually set up, it looks very much like this
is actually PIN_CONFIG_DRIVE_STRENGTH.

Yours,
Linus Walleij
